A-C. or D-C. low-tension distribution for Manhattan?

At the forty-first annual meeting of the Association of Edison Illuminating Companies, held during the week of October 19th, at the Arlington Hotel, Hot Springs, Ark., Mr. Dugald C. Jackson, of the Massachusetts Institute of Technology and past-President of the Institute, presented a valuable paper on the subject of “Electrical Distribution in Very Congested Territory.” Mr. Jackson stated that “the results of comparative analysis of d-c. and a-c, low-tension distribution for Manhattan are notably in favor of the d-c, fortified by storage batteries from a physical standpoint.” He stated that the d-c. distribution system with associated storage batteries has produced a result which is of outstanding service; namely, providing continuous, well-regulated and uninterrupted supply of electric power to the distribution mains through all the vicissitudes of electrical plant operation.
